The Jaguars, who are 12-11 in their last 23 games since a 2-0 start in 2006, now hope they can avoid a letdown against San Diego Sunday.
The home game against the Chargers ends a three-game road trip and the Jaguars need a victory to keep good field position in the AFC wild card race.
The Jaguars and Titans are tied for second place in the AFC South and tied for the two AFC wild card slots at 6-3.
Although the Jaguars won four in a row after losing their opener, they've lost two of their last four but hope to put another run together.
The Jaguars also hope to get quarterback David Garrard back for the Chargers game after he missed three games with a high ankle sprain.
Garrard saw some limited duty in practice last week, but the Jaguars didn't want to rush him back too soon. Garrard said after the Titans game that he'll be back for San Diego, but the club hasn't officially given him the green light yet.
In Garrard's absence, Quinn Gray went 2-1 as a starter, but the Jaguars played it close to the vest. He completed 13 of 23 passes against the Titans for just 101 yards, but he didn't throw any interceptions.
They ran the ball for 166 yards -- Maurice Jones-Drew had 101 yards and Fred Taylor added 45, including a 15-yard run in the first quarter that enabled him to become the 21st player in NFL history with 10,000 career rushing yards.
But the key for the Jaguars was that their defense, shredded for 282 yards rushing in the opener against the Titans and 445 passing yards by Drew Brees last week, held the Titans to 10 net yards.
Now they'll take on LaDainian Tomlinson of the Chargers, although Philip Rivers will give the Chargers the threat of a passing game that the Titans didn't have with Vince Young, who had a 64.8 quarterback rating, threw two interceptions and was sacked four times against the Jaguars.
The Jaguars also showed they could overcome the distractions of some off-the-field problems as linebacker Justin Durant and offensive lineman Richard Collier were suspended for the last two games after being arrested. And Marcus Stroud will be serving the second game of a four-game steroids suspension against the Chargers.
"We talked about the need to be committed to our purpose and to be unified," coach Jack Del Rio said. "It was a big, big win for us today."
The Chargers-Jaguars game will also feature a duel between Tomlinson and Taylor.
Taylor said of reaching the 10,000-yard milestone, "I'd rather it had been a touchdown, but I'm thankful for the way that one happened because it set the tone for the team. They were all jacked up and the O-linemen were so excited. I think it happened in good fashion."
